The Changes in Blood Flow Seen in the Eye after Foot Acupuncture Treatment in Mice

Figure 1

(a) Ocular blood flow was measured by laser speckle flowgraphy under anesthesia. The acupuncture was performed by inserting disposable stainless-steel needles to a depth of approximately 3 mm for 3 minutes. After 3 minutes, the mice were electrically stimulated at 7 mA for 3 minutes using the Picorina, which is an electrical stimulation device that is specifically designed for acupuncture treatment. The needles were removed after the electrical stimulation. Ocular blood flow was measured after each treatment. (b) In the foot acupuncture group, needles were inserted between the thumb and pointer finger and between the annular and little fingers on both feet, which this acupuncture points were used as the treatment for ocular disease. (c) In the sham group, acupuncture needles were inserted into the backs of mice.
